3 MACAddress Table Commands
3.1mac-address-table ageing-timeUse the mac-address-table aging-time global configuration command on the switch to set the length oftime that a dynamic entry remains in the MAC address table after the entry is used or updated. Use theno form of this command to return to the default setting. The aging time applies to all VLANs.

no mac-address-table ageing-time
ageing-time Aging time in seconds. The range is 10 to 1000000 seconds
Command Mode
Global Configuration
